The experiment, which Facebook has now apologized for, might lead
to new policies, including the government regulating these types
of large-scale social media studies, though Warner believes that
might not be the best course of action,
he wrote in his letter to the FTC.

"Further studies like this, without proper oversight or
appropriate review, could have a significant impact upon a large
number of consumers," Warner wrote. Later in his note he added,
"I am not convinced that additional federal regulation in the
answer. Public concerns may be more appropriately addressed
through industry self-regulation." He called these sort of issues
surrounding privacy, social networks, and the law "uncharted
territory."

For now Facebook is continuing its streak of repentance.

"It’s clear that people were upset by this study and we
take responsibility for it," a spokesperson told Re/code.
"The study was done with appropriate protections for
people’s information and we are happy to answer any questions
regulators may have.”
